Pterostegia
Encyclopedia
Pterostegia is a monotypic plant genus containing only the single species Pterostegia drymarioides, which is known as the woodland threadstem or woodland pterostegia. It is native to the western United States. This is a very small annual spreading or climbing plant with very thin, hairy stems. The tiny leaves are lobed or heart-shaped and may be green or pink. The plant may sprawl across the ground in a thin layer or may form small patches here and there. It bears tiny bright pink flowers. The plant is most commonly found carpeting the ground in shady areas, such as in the understory of a cool forest. It sometimes grows hidden from view beneath other plants.
